I'm new Oric baby.
I have 4 modes to work - Oric 1, Oric Atmos, Oric Telstrat (HyperBasic), Oric Telestrat (TeleAss).
I have 16-bit heart - 65C816 and 64K Ram.
Maybe I will have SVideo and composite outputs these days.

I hope you will like me

Best regards,
AtmoStrat

The idea is just to replace the Atmos board with AtmoStrat board and use HuperBasic compiler. 16-bit processor is extra, but unfortunately it don't work with Dos 8D, just with Oric Dos / Sedoric / StratSed. There is no place for MIDI. You just must change 9V PSU with 5V PSU. I hope these are good news for everyone who like to write software for Oric.

About Dos-8D: as I already promised you - I'll replace all 'invalid' cpu instructions, so it will work.
About MIDI: especially for ibisum(!) I foresee to include MIDI support too in my project code name "Oric Communicator". It's work in progress.
And again, well done, jorodr!

The computer is running only in 1 MHz. It's not faster than Atmos and Telestrat and is 100% compatible, just have extended optcodes and address modes. It is useful for that who loves to write in assembler language. I hope there will be interested to find some useful 65C816 cross-assembler. I'm working on to add 64K extra, but it seems it's not easy because of the ULA. Will know soon.

About 7805 - I have replaced it because of the room and because there is a lot of modern 5V PSU-s on the market. I have bought mine PSU adapter a hour before turning on the computer. About the diode - it's not a bad idea, thanks I accept every good idea!

BTW why have you kept the original oric layout? I mean the OpAmp on the 1/Atmos is really badly placed and should be closer to the PSG

I want to keep the max of the Oric spirit and to fit in original Atmos case. Thanks to a friend of mine I have empty Pravetz 8D board and I did a lot of work to capture the schematics from. Then I routed the board following the original. You could see the pictures of the first version of the board with 6502 and 65C816 extension. I wanted to avoid the risk on failure.
Thanks to Fabrice and with his modified Telestrat ROMs was born the idea to make it Telestrat compatible. I have a lot of ideas more, but don't want to talk before to try them Let me try SVideo out first...
